  • Publication number: 20230317174
    Abstract: A memory apparatus and method of operation is provided. The apparatus includes memory cells each connected to one of a plurality of word lines. The memory cells are disposed in strings coupled to one of a plurality of bit lines and are configured to retain a threshold voltage corresponding to one of a plurality of data states.

  • Publication number: 20230298678
    Abstract: A memory system reads data from non-volatile memory cells using a set of read compare voltages to determine which data state the memory cells are in, where each data state is associated with predetermined data values. The read compare voltages are determined dynamically based on a difference between memory cell current at time of programming and memory cell current at time of reading.

  • Publication number: 20230245706
    Abstract: In order to decrease the width of threshold voltage distributions of programmed memory cells without unreasonably increasing the time needed to complete programming, a non-volatile memory uses a zone based program speed adjustment. The non-volatile memory starts programming a first set of the non-volatile memory cells until a minimum number of memory cells of the first set of non-volatile memory cells reach a first threshold voltage. In response to the minimum number of memory cells reaching the first threshold voltage, the first set of non-volatile memory cells are categorized into zones/groups based on threshold voltage. The speed of programming is then adjusted differently for each zone/group and programming is completed for the first set of non-volatile memory cells.

  • Publication number: 20230197168
    Abstract: A system has been described that performs differential temperature compensation based on a differential between the temperature at time of programming and temperature at time of reading for a set of data. Differential temperature compensation is useful for bulk programming/reading (e.g., many pages of data) and/or programming/reading super pages of data (multiple pages residing on different memory die).

  • Publication number: 20230187000
    Abstract: A memory system identifies memory cells connected to a common word line that have had their threshold voltage unintentionally drift lower than programmed by determining whether memory cells meet two criteria: (1) the memory cells have threshold voltages within an offset of a read compare voltage of a data state; and (2) adjacent memory cells (connected to word lines that are adjacent to the common word line) are in one or more low data states. For those memory cells meeting the two criteria, the memory system performs some amount of programming on the memory cells to refresh the data stored in those memory cells to be as originally intended.
